Uses of Coupling AgentCoupling agent is a polymer that binds inorganic fillers to those that should not be able to bond between surfaces. Coupling agent is used as one of the steps to improve the mechanical properties of natural fibers by adding other elements to increase the adhesion of these fibers.
Silane coupling agent is one of the additives to increase the adhesion of the fiber to the matrix. The incorporation of natural fibers into the polymer matrix can increase or decrease the strength of the composite. Natural fiber composites with coupling agents showed higher tensile strength than composites without coupling agents for the same amount of fiber.
The use of a coupling agent changes the reinforcing surface to be hydrophobic so that it can binds polymer well. The formation of bonds between the hydroxyl groups in natural fibers and silane in the matrix and alkoxyl coupling agent groups resulted in increased bonding on the fiber and matrix surfaces and showed an increase in hardness and strength.
If you need a coupling agent, you can use coupling agent tb woods, coupling agent rexnord, and coupling agent falk coupling.
